Why do I feel moody and dizzy when I haven't eaten for more than three hours?

Question

It didn't used to be this way. If I don't eat regularly I feel as though I'm going to pass out and I get really snappy and grumpy.

Answer 1

Hypoglycemia

CAUSES

The carbohydrates we eat are changed into glucose in the digestive system. The glucose passes into the bloodstream and is carried to cells, where it is used to make energy.

Under normal conditions, blood contains just the right amount of glucose. Cells receive all the glucose they need to function properly. But sometimes, blood contains too much or too little glucose. These conditions are called hyperglycemia ("hyper" means "too much") and hypoglycemia ("hypo" means "too little"). Cells either get more glucose than they can use or do not get enough to function normally.

These conditions are caused by two factors. First, a person may eat a diet that provides too much or too little glucose to the body. For example, people who eat a lot of sugar may develop hypoglycemia.

Second, the cells in a person's body may lack the ability to use glucose normally. The person may have inherited the defect from his or her parents. Or something may have happened in the person's life to cause the defect. In either case, the person's blood contains too much or too little glucose. In the latter case, hypoglycemia results.

There is some debate about the nature of idiopathic hypoglycemia. The condition is being diagnosed much less frequently than it was a few decades ago. Some doctors think the condition is caused by other medical problems and is not a disorder in and of itself. Others think that idiopathic hypoglycemia is actually an early stage of diabetes.

SYMPTOMS

Symptoms differ somewhat depending on the type of hypoglycemia that occurs. In the case of drug-induced hypoglycemia, the symptoms may resemble those of extreme shock. They include:

* Cold, pale skin
* Numbness around the mouth
* Anxiety
* Palpitations (irregular heartbeat)
* Emotional outbursts
* Hand tremors (shaking)
* Mental confusion
* Dilated (enlarged) pupils
* Sweating
* Fainting

Answer 2

sounds to me like your sugar is bropping. after an intense and long diet, i was like this too. i think the dieting was too tough on my body and it screwed with my sugar or something. i had to start carrying candy with me, it got bad. after about a year or so of eating healthy food every two hours (a little at a time, obviously) i noticed i was able to go longer without eating. now, two years after it began, i can go a very long time without eating and don't get dizzy or shaky like i used to. i was monitoring my sugar and keeping glucose tabs with me just like diabetics do for awhile. if you don't tell your doctor about this and come up with a plan of action it could turn into diabetis. if this, in fact, is your sugar dropping it is called hypoglycmeia and there are foods you can eat while you are dizzy that will make your sugar go up too fast and therefore you will crash and feel even worse in an hour. if i were you i would go to the doctor, that's what i did and i'm fine now!

Answer 3

Sounds like eating binges prompted by a chemical imbalance.
What was the biggest change that began near the same time it began.

Did you start taking a certain medicine?
Take up a new after school activity?
Start smoking?
etc...

Does diabetes or hypoglycemia run in your family?(numbness, tingling in extremities) You may want to see a Dr.

Answer 4

If a line appears within the time limit, you are pregnant. No matter how "faint". The reason people say "faint" is because the control line is always going to be darker than the test line (90% anyway) because of the fact that the control line HAS to show up. (If you tested right.) That control line will always be there. The other line shows up either only as dark as it can, or lighter due to not enough hormone in your urine (diluted). I think that pregnancy test manufacturers do this on purpose so that we will go and by 10 tests and see if all of them have the "faint" line before we believe we are pregnant. A line is a line. Congrats!!

Answer 5

You could be in early stages of diabetes. You sound like you are having hypoglycemic symptoms. However, if you are just really active, it could be that you need to eat smaller meals more often, every 4 hours or so.

Answer 6

My guess is you are of slim build and have a high metabolic rate, as metioned above i would agree you are probably growing, eat smaller meals more often, your body wants fuel,,feed it!

Answer 7

You're most likely growing
or going through puberty
eat when you're hungry
